Good evening, pool savants
Until about a week ago, my Caretaker 5-port valve worked great at operating the pop-up valves in the floor of the pool (around 22psi). One night I noticed none of the pop-up heads were raised. The pump (Pentair IntelliFlo) is functioning as it always has, and there's the same amount of pressure at the filter (Hayward S244T, 1 year old), approximately 30 psi when the pump is at 3100 rpm.
However, the pressure in the Caretaker is now spiking upto 40 psi and the pop-up heads don't raise up. I bought and installed a new rebuild kit a couple years ago. Do they go bad this quickly? I've taken apart the Caretaker this time and everything seems fine, the pistons don't seem worn out and the gears aren't rattling around or anything.
Any ideas? My sincere appreciation, in advance.
